AI Agent Designs a RISC-V CPU Core From Scratch

Apr 22, 2026IEEE Spectrum AI

Event Summary

In 2020 researchers fine-tuned a GPT-2 model to design fragments of logic circuits; in 2023 researchers used GPT-4 to help design an 8-bit processor with a novel instruction set; by 2024, a variety of LLMs could design and test chips with basic functionality, like dice rolls (though often these were
